74 4 System Bios Adjacent Cache Line Prefetch: The CPU fetches the cache line for 64 bytes if this option is set to Disabled. The CPU fetches both cache lines for 128 bytes as comprised if Enabled. MPS and ACPI MADT Ordering: Allows you to configure the MPS (Multi-Processor Specifi cations) and ACPI settings for your motherboard. Select Modern Ordering if Windows XP or newer is used. Select Legacy Ordering if Windows 2000 or earlier is used. Important: The following feature is only available if supported by the processor and/or operating system. Intel (R) Virtualization Technology: Select Enabled to use Virtualization Technology to allow one platform to run multiple operating systems and applications in independent partitions, creating multiple virtual systems in one physical computer. Important: The following feature is only available if supported by the processor and/or operating system. Execute-Disable Bit Capability: Set to Enabled to enable the Execute Disable Bit which will allow the processor to designate areas in the system memory where an application code can execute and where it cannot, thus preventing a worm or a virus from flooding illegal codes to overwhelm the processor or damage the system during an attack. Important: The following feature is only available if supported by the processor and/or operating system. Simultaneous Multi-Threading: Set to Enabled to use simultaneous multi-threading technology, which will result in increased CPU performance. Active Processor Cores: Set to Enabled to use a processor's second core and beyond. The options are All, 1 and 2. Intel EIST Technology: EIST (Enhanced Intel SpeedStep Technology) allows the system to automatically adjust processor voltage and core frequency in an effort to reduce power consumption and heat dissipation. Please refer to Intel's web site for detailed information. The options are Disable (Disable GV3) and Enable (Enable GV3).
